How to pay Des Moines Water Works bill online step by step
If you are paying online for the first time, start from the official DMWW MyAccount portal. This helps avoid third-party bill payment sites and keeps your payment connected to the correct Des Moines Water Works account.
Open the official MyAccount portal
Go to the official Des Moines Water Works portal here: myaccount.dmww.com.
Choose login, create account, or Pay Bill Now
Log in if you already have an account. Create an account if you want ongoing access. Use Pay Bill Now if you want One Time Pay with no registration required.
Keep your customer and account numbers ready
You need your 7-digit Customer Number and 6-digit Account Number. Enter them with the hyphen between the two numbers, exactly as the MyAccount portal instructs.
Review your bill and payment amount
Check the service address, account number, amount due, and due date before submitting payment. If the amount looks wrong, contact customer service before paying.
Submit payment and wait for confirmation
Complete the payment only after confirming the details. Do not close the payment page until you see a confirmation screen.
Save your receipt
Save the confirmation number, screenshot, or receipt until your payment appears on your DMWW account.
Important pay station warning: DMWW says termination notices are not accepted at pay stations. If you have a termination notice, payment must be made at Des Moines Water Works’ office at 2201 George Flagg Parkway, Des Moines. Pay station payments can take up to 10 days to be received by DMWW.

How DMWW MyAccount and mobile tools help
The DMWW MyAccount portal is useful if you want more than a quick payment. The portal explains that customers can track and compare water usage, create alerts, and access data across devices. DMWW also has a MyAccount mobile app that lets customers view and pay bills, sign up for alerts, view usage, and use convenient payment features.
If you previously registered on an older payment site, the new MyAccount page says previous users may need to reset their password using the “Forgot your Password?” link.
- Open the official DMWW MyAccount portal.
- Create an account using the name on the account and Customer-Account Number.
- Enter your Customer Number and Account Number with the hyphen between them.
- Use One Time Pay if you only need to pay once.
- Use alerts to monitor higher-than-usual water use.
- Use usage history to spot leaks, irrigation spikes, or unusual household consumption.
- Save payment confirmation after each payment.
Practical advice: If your due date is close, use the official MyAccount portal or call DMWW. Do not use a pay station for urgent or termination-notice payments because the account is not credited until DMWW receives the payment.
